  Now, in a tire in which a metal rim is fitted in the rubber part, the rim can be pressed and disassembled as in the technique shown in Patent Document 4 above. However, a tire in which a rubber part is bonded to a metal base part cannot be easily disassembled even if the base part is simply pressed. Therefore, there is a problem that it takes much time to dispose and reuse such tires.

  Accordingly, an object of the present invention is to suitably separate waste tires formed by bonding a rubber portion to a base portion and to facilitate reuse of each.

  In order to achieve the above object, the present invention is a waste tire processing apparatus for processing a tire comprising a cylindrical metal base portion and a rubber portion bonded to the outer periphery of the base portion. A support table on which the tire is placed while supporting the base portion, a cutter installed so as to face the rubber portion in the axial direction of the tire in a state of being placed on the support table, A heater that heats the base portion from the inside in a placed state, a press that presses the rubber portion toward the cutter from the side opposite to the cutter, and a controller that controls the heater and the press. The control device is configured to heat the base portion to a predetermined temperature by the heater, operate the press to press the rubber portion to separate it from the base portion, and press it against the cutter. It has a configuration which is characterized in that the cross-sectional.

  According to the present invention, since the rubber part is pressed with the press after the base part is heated by the heater, the rubber part can be reliably separated from the base part, and each can be recovered and reused. Can do. Moreover, since the separated rubber part is cut as it is by the cutter, the recovered rubber part can be easily stored and transported, and the rubber part can be easily reprocessed. In addition, the separation of the base and rubber parts and the cutting of the rubber parts are performed by a series of press movements, so work efficiency is good and the same press is used, so installation space and cost are reduced. It is done.

  The support base is formed in a cylindrical shape or a columnar shape, and its end in the axial direction comes into contact with the end surface and the inner surface of the base portion to support the base portion, and the cutter surrounds the support base. It can be arranged radially. If it does in this way, a base part can be certainly supported by simple composition, and a rubber part can be cut effectively.

  In the above configuration, the heater includes a coil disposed in the base portion in a state of being placed on the support base, and a power supply device for energizing the coil, and the control device includes the tire Can be heated by energizing the coil with the power supply device in a state of being mounted on the support base.

  Further, in the above configuration, the heater is provided so as to be movable in the axial direction of the tire when placed on the support base, and a coil that is taken in and out of the base portion, and a power source that energizes the coil. The control device moves the coil into the base portion in a state where the tire is placed on the support base, and energizes the coil by the power supply device to move the base portion. The coil can be heated and then moved out of the base.

  If it does in this way, when mounting the tire which is going to be processed on a support stand, or when collect | recovering the base part and rubber | gum part after processing, it can prevent a coil from interfering with work. . In addition, by moving the coil into the base portion and then starting to heat the base portion by energizing the coil, unnecessary power consumption can be suppressed, and only the base portion can be efficiently heated.

  In the above configuration, if the power supply device allows high-frequency current to flow through the coil during energization, only the base portion made of metal can be intensively heated by induction heating, so that power consumption is suppressed. As a result, the time required for tire processing as a whole can be shortened.

  Further, in the above configuration, the press includes a pressing tool that contacts the axial end surface of the rubber portion and presses the rubber portion, and a drive device that moves the pressing tool in the axial direction of the tire. The pressing tool is formed in a concave shape so as to face the base portion in a state of being placed on the support base, and includes an opening that can accommodate the base portion when pressing the rubber portion. It can be.

  In this way, even if the pressing tool is moved in the axial direction of the tire, the base part is accommodated in the opening, so that the rubber part is pressed from the base part without contacting the pressing tool and the base part. Can be separated.

  As described above, according to the present invention, the rubber part can be reliably separated from the base part, and further, the separated rubber part can be cut and collected by a cutter, and each can be easily reused. Moreover, since separation and cutting are performed by a series of movements of the press, the waste tire can be processed efficiently.

  Embodiments of the present invention will be described below with reference to the drawings.

The waste tire processing apparatus 100 according to the first embodiment processes a used tire T, and heats a processing table 110 on which the tire T is placed and a base portion B of the placed tire T. A heater 120, a press 130 that presses the rubber part G of the tire T, and a control panel 140 that controls the heater 120 and the press 130 are provided.
Here, as shown in FIG. 1, the tire T includes a metal base portion B and a rubber portion G bonded to the base portion B, and the base portion B is formed in a cylindrical shape on the outer surface thereof. The rubber part G is bonded.

  As shown in FIG. 1, the processing table 110 includes a base 111, a support base 112 standing on the base 111, and a cutter 113 provided side by side on the support base 112.

  The support base 112 is formed in a cylindrical shape as a whole, and is provided so that its axial direction is perpendicular to the base 111. The upper end portion of the support base 112 is formed so as to be in contact with the lower end surface and the inner side surface of the base portion B, and the base portion B is supported on the upper end portion, whereby the tire T is placed horizontally on the support base 112. The Therefore, in a state where the tire T is placed on the support base 112, the axial direction of the tire T and the axial direction of the support base 112 coincide with each other, and the central axes thereof are substantially the same axis. The hollow portion of the support base 112 is formed so that its inner diameter is somewhat smaller than the inner diameter of the base portion B, and a coil 121 described later can be accommodated in this hollow portion. The cutters 113 are erected along the outer surface of the support base 112. In the first embodiment, twelve cutters 113 are radially arranged at equal intervals in the circumferential direction.

  The heater 120 includes a coil 121 supported so as to be movable up and down, a power supply device 122 that causes a high-frequency alternating current to flow through the coil 121, an elevating device 123 that moves the coil 121 up and down, and a current sensor that detects a current flowing through the coil 121. 124 and a position sensor 125 for detecting the vertical position of the coil 121.

The outer diameter of the coil 121 is formed to be somewhat smaller than the inner diameter of the base portion B of the tire T, and can be taken in and out of the base portion B. The outer diameter of the coil 121 is somewhat smaller than the hollow portion of the support base 112, and can be taken in and out of the hollow portion. When a high-frequency current flows from the power supply device 122 to the coil 121, a high-frequency eddy current is generated in the conductor (base portion B) around the coil 121 and generates heat. That is, heating by the heater 120 is performed by generating heat not in the coil 121 but in the conductor (base part B). The current at this time is detected by the current sensor 124 and transmitted to the control panel 140 as shown in FIG. Based on this, the control panel 140 controls the power supply device 122 so that the conductor (base portion B) is heated at a preset temperature, and adjusts and maintains the current flowing through the coil 121.
The coil 121 can be moved up and down separately from a pressing tool 131 described later. When the lifting device 123 is operated, the coil 121 moves up and down and its vertical position changes. The position of the coil 121 in the vertical direction is detected by the position sensor 125 and transmitted to the control panel 140 as shown in FIG. Based on this, the control panel 140 controls the lifting device 123 so that the coil 121 stops at a predetermined position.

  The press 130 includes a pressing tool 131 that contacts the rubber part G of the tire T, a hydraulic cylinder 132 that moves the pressing tool 131 up and down, a pump 133 that supplies and recovers hydraulic oil to the hydraulic cylinder 132, and a pressing tool 131. And a position sensor 134 for detecting the position in the vertical direction.

  The pressing tool 131 has a concave opening 131a formed downward in the center thereof, and a peripheral portion of the opening 131a is in contact with the rubber part G. The opening 131a has an inner diameter slightly larger than the outer diameter of the base portion B of the tire T and a depth dimension larger than an axial length dimension of the base B. When pressing G, the base B can be accommodated in the opening 131a.

  In the first embodiment, as shown in FIG. 1, two hydraulic cylinders 132 are provided, and when hydraulic oil is supplied from the pump 133 to the hydraulic cylinder 132, the hydraulic cylinder 132 extends and the pressing tool 131. When the hydraulic oil is recovered from the hydraulic cylinder 132 by the pump 133, the hydraulic cylinder 132 is shortened and the pressing tool 131 is moved upward. The vertical position of the pressing tool 131 is detected by the position sensor 134 and is transmitted to the control panel 140 as shown in FIG. Based on this, the control panel 140 controls the pump 133 so that the pressing tool 131 moves in a predetermined vertical direction.

  The control panel 140 includes a start switch 141 and a stop switch 142 that are operated by an operator, and a controller 143 that controls the heater 120 and the press 130 in response to the operation of these switches.

As shown in FIG. 2, the controller 143 receives signals from the current sensor 124, the position sensor 125, and the position sensor 134 together with signals from the start switch 141 and the stop switch 142, and the controller 143 receives the signals from the current sensor 124. The power supply device 122 is controlled according to the signal, the lifting device 123 is controlled according to the signal from the position sensor 125, and the pump 133 is controlled according to the signal from the position sensor 134.
When the start switch 141 is operated, the controller 143 activates the heater 120 and the press 130 as described later in accordance with signals from the sensors. When the stop switch 142 is operated, the controller 143 stops the heater 120 and the press 130 and interrupts or ends the processing of the tire T.

Now, as shown in FIG. 3, when the start switch 141 is operated with the tire T placed on the support base 112 of the processing table 110 (YES in S10), the controller 143 operates the lifting device 123. The coil 121 is lowered to position the coil 121 in the base portion B as shown in FIG. 4 (i) (S11). That is, the controller 143 operates the lifting / lowering device 123 until the vertical position of the coil 121 detected by the position sensor 125 reaches the stop position of the coil 121 within the preset base portion B.
When the coil 121 is positioned at the stop position in the base portion B, the controller 143 operates the power supply device 122 to energize the coil 121 and heats the base portion B from the inside (S12). At this time, the power supply device 122 is controlled so that the current value detected by the current sensor 124 matches the current value when the base portion B is heated to a set temperature (for example, 200 ° C.). The heating to the base part B is continuously performed for a preset time (S13), whereby the adhesive force between the base part B and the rubber part G is weakened.

When the time set in the heating state has passed (YES in S13), the controller 143 stops energization of the coil 121 by the power supply device 122 and operates the lifting / lowering device 123 to lower the coil 121. ), The coil 121 is positioned in the support base 112 (S14). That is, the controller 143 operates the lifting / lowering device 123 until the vertical position of the coil 121 detected by the position sensor 125 reaches the preset stop position of the coil 121 in the support base 112.
Subsequently, the controller 143 operates the pump 133 to extend the hydraulic cylinder 132 and lower the pressing tool 131. As shown in FIG. 4 (ii), the pressing tool 131 is further lowered even after the pressing tool 131 comes into contact with the rubber part G of the tire T, and comes into contact with the cutter 113 as shown in FIG. 4 (iii). The pressing tool 131 is lowered until it is done (S15). That is, the controller 143 supplies hydraulic oil from the pump 133 to the hydraulic cylinder 132 until the vertical position of the pressing tool 131 detected by the position sensor 134 reaches a predetermined contact position with the cutter 113. Thereby, the rubber part G is separated from the base part B and cut by the cutter 113.
When the cutting of the rubber part G is finished, the controller 143 operates the lifting / lowering device 123 to raise the coil 121, and also operates the pump 133 to raise the pressing tool 131 to return each to the initial position (S16). That is, the elevating device 123 and the pump 133 are controlled so that the detected vertical positions of the coil 121 and the pressing tool 131 are the preset initial positions.

  After processing the tire T in this way, the base part B is recovered as it is, and the rubber part G is recovered in a state of being cut into blocks.

  According to the first embodiment, since the base part B is heated by the heater 120 and the rubber part G is pressed by the press 130, the rubber part G can be reliably separated from the base part B. Since the separated rubber part G is cut into blocks by the cutter 113, the base part B and the rubber part G can be collected separately and can be easily reprocessed. Moreover, since the separation step and the cutting step are executed by a series of movements of the press 130, the work efficiency is good, and the same press 130 is used, so that the installation space and cost of the waste tire processing apparatus 100 as a whole can be suppressed. .

  Further, according to the first embodiment, the base portion B can be reliably supported on the support base 112 and separated from the rubber portion G, and the rubber portion G can be effectively cut by the cutter 113. Further, when the cutting of the rubber part G is finished, the coil 121 and the pressing tool 131 are raised and returned to the initial position. Therefore, when the tire T to be processed next is placed on the support base 112, the processing is performed. It is possible to prevent the coil 121 and the pressing tool 131 from interfering with work when the subsequent base B and rubber G are collected. In addition, since the coil 121 is moved into the base portion B and then the coil 121 is energized and the base portion B is heated by induction heating, the processing time can be shortened by intensively heating the base portion B. At the same time, unnecessary power consumption is suppressed.

  The waste tire processing apparatus 200 according to the second embodiment includes a processing table 210 on which the tire T is placed, a heater 220 that heats the base portion B of the placed tire T, and a press that presses the rubber portion G of the tire T. 230 and a control panel 240, and further includes a transport table 250 for transporting the tire T.

  The support base 212 is formed in a cylindrical shape as a whole, and is provided so that its axial direction is perpendicular to the base 211. The upper end portion of the support base 212 is formed so as to be in contact with the lower end surface and the inner side surface of the base portion B, and the tire T is placed horizontally on the support base 212 by supporting the base portion B on the upper end portion. . Therefore, in a state where the tire T is placed on the support base 212, the axial direction of the tire T and the axial direction of the support base 212 coincide with each other, and the central axes thereof are substantially the same axis. The cutters 213 are erected along the outer surface of the support base 212. In the second embodiment, twelve cutters 213 are arranged radially at equal intervals in the circumferential direction.

When a high-frequency current flows through the coil 221 from the power supply device 222, the conductor (base part B) generates heat and is heated by the heater 220 as in the first embodiment. The current at this time is detected by the current sensor 223 and is transmitted to the control panel 240 as shown in FIG. Based on this, the control panel 240 controls the power supply device 222 so that the conductor (base portion B) is heated at a preset temperature, and adjusts and maintains the current flowing through the coil 221.

  The press 230 includes a pressing tool 231 that contacts the rubber part G of the tire T, a hydraulic cylinder 232 that moves the pressing tool 231 up and down, a pump 233 that supplies and recovers hydraulic oil to the hydraulic cylinder 232, and a pressing tool.

The opening 231 a has an inner diameter slightly larger than the outer diameter of the base portion B of the tire T and a depth dimension larger than the axial length of the base B. When pressing G, the base B can be accommodated in the opening 231a.

  The support 235 is formed in an L shape in a sectional view including a floor portion on which the tire T is placed and a pillar portion connecting the floor portion to the pressing tool 231, and moves up and down integrally with the pressing tool 231. To do. The floor portion of the support 235 is formed in a flat plate shape, and a hole slightly larger than the outer diameter of the support base 212 is formed at the center thereof, and a slit that is continuously aligned with the arrangement of the cutter 213 is formed in the hole. Is formed. Thereby, the support tool 235 can be moved downward without contacting the support base 212 and the cutter 213. Further, the hole in the floor is opened at least toward the transfer table 250, and the loading platform 252 of the transfer table 250 can pass through this opening.

  In the second embodiment, as shown in FIG. 5, one hydraulic cylinder 232 is provided, and when hydraulic oil is supplied from the pump 233 to the hydraulic cylinder 232, the hydraulic cylinder 232 extends and the pressing tool 231. When the support 235 moves downward and the hydraulic oil is recovered from the hydraulic cylinder 232 by the pump 233, the hydraulic cylinder 232 is shortened and the pressing tool 231 and the support 235 move upward. The vertical position of the pressing tool 231 is detected by the position sensor 234 and transmitted to the control panel 240 as shown in FIG. Based on this, the control panel 240 controls the pump 233 so that the pressing tool 231 moves in a predetermined vertical direction.

  The control panel 240 includes a start switch 241 and a stop switch 242 that are operated by an operator, and a controller 243 that controls the heater 220, the press 230, and the transfer table 250 in response to the operation of these switches.

As shown in FIG. 6, the controller 243 receives signals from the start sensor 241 and the stop switch 242 as well as signals from the current sensor 223 and the position sensors 234, 254, and 256, and the controller 243 receives the signal from the current sensor 223.

The slide device 255 is controlled.
When the start switch 241 is operated, the controller 243 activates the heater 220, the press 230, and the transfer table 250 as described later in accordance with signals from the sensors. When the stop switch 242 is operated, the controller 243 stops the heater 220, the press 230, and the transfer table 250, and interrupts or ends the processing of the tire T.

  As shown in FIG. 5, the transport table 250 includes a guide 251 that is supported so as to be movable up and down with respect to a base (not shown), a loading platform 252 that is slidably supported by the guide 251, and an elevator 253 that moves the guide 251 up and down. A position sensor 254 that detects the vertical position of the guide 251 relative to the base, a slide device 255 that horizontally moves the loading platform 252 along the guide 251, and a position sensor 256 that detects the horizontal position of the loading platform 252 relative to the guide 251. Is provided.

The loading platform 252 is slidable in the distal end direction and the proximal end direction, and supports the tire T at the distal end side portion. Further, the cargo bed 252 is formed to be somewhat narrower than the outer diameter of the tire T (the outer diameter of the rubber part G) so that it can pass vertically through the opening formed in the floor of the support 235 described above. Has been made.
When the elevating device 253 is operated, the loading platform 252 moves up and down together with the guide 251 and its vertical position changes. The position of the guide 251 in the vertical direction is detected by the position sensor 254 and transmitted to the control panel 240 as shown in FIG. Based on this, the control panel 240 controls the elevating device 253 so that the guide 251 stops at a predetermined position. Further, when the slide device 255 is actuated, the loading platform 252 moves in the distal direction or the proximal direction, and its horizontal position changes. The horizontal position of the loading platform 252 is detected by the position sensor 256 and transmitted to the control panel 240 as shown in FIG. Based on this, the control panel 240 controls the slide device 255 so that the loading platform 252 stops at a predetermined position.

Now, as shown in FIG. 7, when the start switch 241 is operated (YES in S20), the controller 243 activates the transfer table 250 to display one of the used tires in a predetermined storage location. As shown in (i) of FIG. 8, it is transferred to the support 235 (S21). That is, in a state where the tire T to be processed is placed on the loading platform 252, the tire T is moved to a position slightly above the floor of the support 235, and the loading platform 252 is slid to the tip side as it is, so that the tire T is substantially at the center of the support 235. To be located. Then, by lowering the loading platform 252, only the loading platform 252 passes through the support tool 235, and the tire T is placed on the support tool 235. When the controller 243 retracts the loading platform 252 from below the support 235, the controller 243 operates the pump 233 to extend the hydraulic cylinder 232 and lower the pressing tool 231. In this way, the tire T is transferred from the support 235 to the support base 212 (S22). That is, the pressing tool 231 is lowered until the floor portion of the support tool 235 is below the upper end portion of the support base 212 and stopped before the pressing tool 231 contacts the rubber portion G of the tire T.
When the descent stops, the controller 243 activates the power supply device 222 to energize the coil 221 and heats the base portion B from the inside (S23). At this time, the power supply device 222 is controlled so that the current value detected by the current sensor 224 matches the current value when the base portion B is heated to a set temperature (for example, 200 ° C.). The heating to the base part B is continuously performed for a preset time (S24), whereby the adhesive force between the base part B and the rubber part G is weakened.

When the time set in the heating state has passed (YES in S24), the controller 243 stops energization of the coil 221 by the power supply device 222 and operates the pump 233 to lower the pressing tool 231. As shown in FIG. 8 (ii), the pressing tool 231 is further lowered even after the pressing tool 231 comes into contact with the rubber part G of the tire T, and as shown in FIG. 8 (iii), it comes into contact with the cutter 213. The pressing tool 231 is lowered until it is done (S25). That is, the controller 243 supplies hydraulic oil from the pump 233 to the hydraulic cylinder 232 until the vertical position of the pressing tool 231 detected by the position sensor 234 reaches a preset contact position with the cutter 213. Thereby, the rubber part G is separated from the base part B and cut by the cutter 213.
When the cutting of the rubber part G is finished, the controller 243 operates the pump 233 to raise the pressing tool 231 and return it to the initial position (S26). That is, the pump 233 is controlled so that the vertical direction position of the pressing tool 231 becomes a preset initial position.

  After processing the tire T in this way, the base part B is recovered as it is, and the rubber part G is recovered in a state of being cut into blocks.

  According to the second embodiment, since the base part B is heated by the heater 220 and the rubber part G is pressed by the press 230, the rubber part G can be reliably separated from the base part B. Since the separated rubber part G is cut into a block shape by the cutter 213, the base part B and the rubber part G can be collected separately and can be easily reprocessed. In addition, since the separation process and the cutting process are performed by a series of movements of the press 230, the work efficiency is high, and the same press 230 is used, so that the installation space and cost of the waste tire processing apparatus 200 as a whole can be suppressed. .

  Further, according to the second embodiment, the base portion B can be reliably supported on the support base 212 and separated from the rubber portion G, and the rubber portion G can be effectively cut by the cutter 13. In addition, since the coil 221 is inserted into the base part B and then the coil 221 is energized and the base part B is heated by induction heating, the base part B can be heated intensively to shorten the processing time. At the same time, unnecessary power consumption is suppressed. Of course, since the tire T is placed on the support base 212 using the press 230 and the transfer table 250, it is not necessary to manually lift the tire T, which is a heavy object, and labor is reduced.

  In the second embodiment, the tire T to be processed is transported by the transport table 250. However, other handling devices such as a robot arm may be used, and the separated base B and rubber G may be used. You may make it use these handling apparatuses also in collect | recovering. Of course, in the first embodiment, the handling device may be used for placing the tire T on the support base 112 and collecting the base portion B and the rubber portion G.

  In the first and second embodiments, the tire T having a specific size is placed on the support bases 112 and 212 for processing, but the upper ends of the support bases 112 and 212 can be adjusted in the radial direction. The diameter of the tire can be changed, or the upper end can be exchanged with one having a different diameter. Furthermore, although the cutters 113 and 213 in the first and second embodiments are rectangular in side view, the cutter in the present invention is not limited to such a form.
